The flat face 17 is pierced with an oblong day 19 extending to the level of the inner wall 20 of the lower expander 8 from the shortest part 21 to the longest part 22. The lower expander 9 of the lower fixing means 5 is substantially in the form of a truncated cylinder, its flat face 23 being turned downwards. Its bias face 24 being open, the planar face 23 is traversed by a tapped hole 25 eccentric towards the shortest part 26 of the expander 9. Said hole 25 which has an upper chamfer 27 has an axis substantially parallel to the axes of the threaded rod 1 and of the lower fixing means 6. The upper expander 10 of the lower fixing means 6 is substantially in the form of a truncated cylinder, its flat face 28 being turned upwards. Its bias face 29 being open, the planar face 28 is crossed by an oblong day 30 extending from the shortest part 31 to the longest part 32.
Le trou 25, taraudé reçoit la partie filetée inférieure de la tige de liaison 1 , qui traverse le jour oblong 30 de l'expandeur 10. Les faces de biais 24 etThe threaded hole 25 receives the lower threaded part of the connecting rod 1, which crosses the oblong day 30 of the expander 10. The bias faces 24 and
29 coulissent les unes sur les autres de manière à ce que les axes des expandeurs 9 et 10 s'écartent l'un de l'autre en restant parallèle à l'axe de la tige 2.29 slide over one another so that the axes of the expanders 9 and 10 move away from each other while remaining parallel to the axis of the rod 2.
Ce déplacement, sous l'effet du serrage par vissage de la tige 1 , sur l'expandeur inférieur 9 augmente la surface horizontale pour venir solidariser fixement les expandeurs 9, 10 contre la paroi intérieure du tube 3, par contrainte. Ce serrage permet le blocage du moyen de fixation inférieur 6 sur la paroi intérieure 33 du tube de cadre 3 qui de ce fait devient le support fixe. Lors de ce déplacement, la tige 1 se déplace latéralement dans l'expandeur supérieur 10 sous l'effet du déplacement longitudinal et latéral de celui-ci sur l'expandeur inférieur 9, sous l'action de vissage de la tige filetée 1. L'action rotative de la tige de liaison 1 actionne le moyen de fixation inférieur 6 pour assurer le serrage du point fixe inférieur dans le tube 3.This displacement, under the effect of the tightening by screwing of the rod 1, on the lower expander 9 increases the horizontal surface to come fixedly secure the expanders 9, 10 against the inner wall of the tube 3, by constraint. This tightening allows the locking of the lower fixing means 6 on the inner wall 33 of the frame tube 3 which therefore becomes the fixed support. During this movement, the rod 1 moves laterally in the upper expander 10 under the effect of the longitudinal and lateral movement of the latter on the lower expander 9, under the screwing action of the threaded rod 1. L the rotary action of the connecting rod 1 actuates the lower fixing means 6 to ensure the tightening of the lower fixed point in the tube 3.
Le moyen de fixation inférieur 6 est placé dans le tube du cadre 3 à une distance au moins égale à la possibilité de coulissement de la tige de selle 2 souhaitée. Cette distance est peu différente de la longueur de la tige de selle 2.The lower fixing means 6 is placed in the tube of the frame 3 at a distance at least equal to the possibility of sliding of the seat post 2 desired. This distance is little different from the length of the seatpost 2.
Le moyen de guidage et d'arrêt supérieur 5 se logeant dans la tige de selle 2 est composé de deux expandeurs 7, 8 distincts, il est contrairement au moyen de fixation inférieur 6, placé indépendamment de la tige de liaison 1 dans la tige de selle 2. Ainsi, la tige 1 relie deux parties fixes solidaires respectivement de la tige de selle 2 et du tube du cadre 3 à l'aide des moyens de fixation supérieur 5 et inférieur 6.The upper guide and stop means 5 housed in the seatpost 2 is composed of two separate expanders 7, 8, it is unlike the lower fixing means 6, placed independently of the connecting rod 1 in the seatpost saddle 2. Thus, the rod 1 connects two fixed parts secured respectively to the seat rod 2 and to the tube of the frame 3 using the upper 5 and lower 6 fixing means.
Le moyen de guidage et d'arrêt supérieur 5 comprend une vis creuse 34. La tige 1 coulisse au traverse du creux de la vis 34 dont la tête 35 vient appuyer sur la face inférieure 17 de l'expandeur inférieur 8 du moyen de guidage et d'arrêt supérieur 5.The upper guide and stop means 5 comprises a hollow screw 34. The rod 1 slides through the hollow of the screw 34, the head 35 of which presses on the lower face 17 of the lower expander 8 of the guide means and upper stop 5.
Sous l'effet du vissage de la vis creuse 34, l'expandeur inférieur 8 vient coulisser sur la face de biais de l'expandeur supérieur 7 en un déplacement longitudinal et latéral jusqu'au contact de la paroi intérieure de la tige de selle 2.Under the effect of the screwing of the hollow screw 34, the lower expander 8 comes to slide on the bias face of the upper expander 7 in a longitudinal and lateral movement until contact with the inner wall of the seat post 2 .
Chaque expandeur 7, 8 appuyant de façon opposée sur la face interne de la tige de selle 2.Each expander 7, 8 pressing oppositely on the internal face of the seatpost 2.
Le montage du dispositif selon l'invention s'effectue de la manière suivante : Le serrage de l'expandeur inférieur du moyen inférieur vissé sur le bas de la tige de liaison filetée est effectué en actionnant le boulon borgne 37 vissé au sommet de la tige filetée 1. On place le moyen de guidage et d'arrêt supérieur 5 dans la tige de selle 2, en actionnant la vis creuse. Après avoir dévisser le boulon borgne 37, ladite tige filetée 1 est passée dans le perçage de la vis creuse du moyen de guidage et d'arrêt supérieur 5 placé dans la tige de selle 2 et à partir de l'ouverture de la partie supérieure de la tige de selle 2, on replace la gaine et le boulon borgne servant de butée.The assembly of the device according to the invention is carried out in the following manner: The tightening of the lower expander of the lower means screwed onto the bottom of the threaded connecting rod is carried out by actuating the blind bolt 37 screwed to the top of the rod threaded 1. The upper guide and stop means 5 are placed in the seatpost 2, by actuating the hollow screw. After unscrewing the blind bolt 37, said threaded rod 1 is passed through the bore of the hollow screw of the upper guide and stop means 5 placed in the seat post 2 and from the opening of the upper part of the seat post 2, the sheath and the blind bolt serving as a stopper are replaced .
Afin de garantir le non dépassement de la zone au-delà de laquelle le réglage de la tige de selle 2 vers la position la plus haute devient dangereux, le dispositif selon l'invention se caractérise en ce qu'une gaine 36 enserre la partie supérieure de la tige de liaison 1 , entre le moyen de fixation de la tige de selle et un boulon borgne 37 placé à l'extrémité supérieure de la tige de liaison 1. Cette gaine 36 agit également comme amortisseur en cas de tentative de vol. Un boulon autobloquant 38 vissé sur la parie inférieure de la tige 1 appuie sur la face plane 28 de l'expandeur 10. Suivant d'autres caractéristiques :In order to guarantee that the area beyond which the adjustment of the seatpost 2 towards the highest position becomes dangerous is not exceeded, the device according to the invention is characterized in that a sheath 36 encloses the upper part of the connecting rod 1, between the means for fixing the seat post and a blind bolt 37 placed at the upper end of the connecting rod 1. This sheath 36 also acts as a shock absorber in the event of attempted theft. A self-locking bolt 38 screwed on the lower part of the rod 1 presses on the flat face 28 of the expander 10. According to other characteristics:
- une lame de ressort 39 est fixée à l'une de ses extrémités en bordure de la partie supérieure de l'expandeur supérieur 7 du moyen de guidage et d'arrêt supérieur 5 de la tige de selle. La lame de ressort présente une ouverture, en particulier délimitée entre deux doigts, à son autre extrémité. La tige de liaison 1 , munie de son boulon borgne 37 à son extrémité supérieure traverse la vis creuse, vient au contact de la lame de ressort laquelle se soulève guidée par les bossages 16, 16' pour laisser passer le boulon 37 et se replace en enserrant la tige de liaison 1 , interdisant ainsi la possibilité de ressortir. Cette lame de ressort 39 résout le problème posé par les tiges de selles 2 monoblocs qui interdisent l'accès par le haut.- A spring leaf 39 is fixed at one of its ends bordering the upper part of the upper expander 7 of the upper guide and stop means 5 of the seat post. The leaf spring has an opening, in particular delimited between two fingers, at its other end. The connecting rod 1, provided with its blind bolt 37 at its upper end passes through the hollow screw, comes into contact with the leaf spring which lifts guided by the bosses 16, 16 ′ to allow the bolt 37 to pass and is replaced by enclosing the connecting rod 1, thus preventing the possibility of coming out. This leaf spring 39 solves the problem posed by the two-piece seat posts 2 which prevent access from the top.
- les expandeurs son munis de rainures longitudinales 40, ces rainures venant au contact du cordon de soudure se trouvant très généralement à l'intérieur des tubes 2, 3, afin de faciliter le serrage.- Sound expanders provided with longitudinal grooves 40, these grooves coming into contact with the weld bead being very generally located inside the tubes 2, 3, in order to facilitate tightening.
Il ressort de ce qui précède que les avantages du dispositif selon l'invention sont nombreux : il est simple, robuste, facile à installer, il ne nécessite aucune modification ou moyen d'adaptation particulier sur les tubes 2, 3 employés dans la fabrication de cycles, aucun percement n'est nécessaire.It appears from the above that the advantages of the device according to the invention are numerous: it is simple, robust, easy to install, it does not require any modification or particular means of adaptation on the tubes 2, 3 used in the manufacture of cycles, no drilling is necessary.
Un autre avantage est certainement son efficacité puisqu'il est installé à l'intérieur des tubes 2, 3 et donc non accessible. En luttant plus efficacement contre le vol, le handicap majeur pour la pratique urbaine du vélo, il contribue au développement de l'utilisation du vélo comme mode de transport.Another advantage is certainly its efficiency since it is installed inside the tubes 2, 3 and therefore not accessible. By fighting more effectively against theft, the major handicap for urban cycling, it contributes to the development of the use of bicycles as a mode of transport.
